5.3.5 The Menstrual Cycle

• The menstrual phase involves the shedding of the uterine lining.


  True
• The menstrual cycle is essential for female fertility.


  True
• LH triggers the release of a mature egg from the ovary.


  True
• The corpus luteum secretes progesterone and estrogen to maintain the endometrium.
• FSH stimulates the development of egg follicles in the ovaries during the follicular phase.
• What is the primary role of FSH in the follicular phase of the menstrual cycle?

  Develop egg follicles
• What hormone triggers ovulation in the menstrual cycle?

  LH
• What does LH convert the empty follicle into after ovulation?

  Corpus luteum
• Arrange the phases of the menstrual cycle in their correct order:

  1️⃣ Menstrual

  2️⃣ Follicular

  3️⃣ Ovulation

  4️⃣ Luteal
• During the follicular phase, FSH stimulates the development of egg follicles in the ovaries
• FSH stimulates the thickening of the uterine lining.

  False
• Estrogen is responsible for thickening the endometrium
• Match each hormone with its source and role in the menstrual cycle:

  FSH ↔️ Pituitary Gland - Stimulates follicle development

  LH ↔️ Pituitary Gland - Triggers ovulation

  Estrogen ↔️ Ovaries - Thickens uterine lining

  Progesterone ↔️ Corpus Luteum - Maintains endometrium
• LH is produced by the pituitary
• What triggers the release of a mature egg from the follicle during ovulation?

  LH surge
• Progesterone is produced by the corpus luteum
• What is the role of estrogen in thickening the uterine lining?

  Prepares for pregnancy
• Estrogen contributes to the development of female secondary sexual characteristics during puberty.


  True
• Progesterone is produced primarily by the corpus luteum.
• Progesterone inhibits the release of FSH and LH during the luteal phase.


  True
• Progesterone suppresses new follicle development by inhibiting the release of FSH and LH.
• The menstrual cycle typically lasts around 28 days.

  True
• Which hormone triggers ovulation?

  LH
• Match the hormone with its role in the menstrual cycle:

  FSH ↔️ Stimulates egg follicle development

  LH ↔️ Triggers ovulation

  Estrogen ↔️ Thickens uterine lining

  Progesterone ↔️ Maintains uterine lining
• Luteinizing Hormone (LH) triggers ovulation
• Progesterone secretion is promoted by the corpus
• Estrogen is primarily produced by the ovaries.


  True
• The menstrual cycle typically lasts 28 days.
• Match the hormone with its primary role in the menstrual cycle:

  FSH ↔️ Stimulates egg follicle development

  LH ↔️ Triggers ovulation

  Estrogen ↔️ Thickens the endometrium

  Progesterone ↔️ Maintains the thickened endometrium
• FSH stimulates the development of egg follicles in the ovaries.
• Arrange the phases of the menstrual cycle in the correct order:

  1️⃣ Menstrual phase

  2️⃣ Follicular phase

  3️⃣ Ovulation

  4️⃣ Luteal phase
• Fluctuating hormone levels regulate the phases of the menstrual cycle.


  True
• LH triggers the release of a mature egg from the ovary.

  True
• Follicle-Stimulating Hormone (FSH) is produced by the pituitary
• LH is responsible for triggering ovulation
• LH, FSH, and estrogen work together to prepare the uterus for pregnancy.


  True
• What happens to the uterine lining during the menstrual phase of the menstrual cycle?

  It is shed
• Match the key processes in the menstrual cycle with their descriptions:

  Uterine Lining Thickening ↔️ The endometrium thickens to support implantation

  Ovulation ↔️ A mature egg is released from the ovary

  Hormone Regulation ↔️ Fluctuating hormone levels maintain the cycle
• Which hormone triggers ovulation?

  LH
• Progesterone maintains the thickened endometrium.
